The answer is to provide alt text for all visual elements, ensure high color contrast, and set a logical tab order. These three best practices for accessibility in Power BI reports directly support users with visual impairments or those relying on screen readers. Alt text gives screen readers a textual description of charts and images, high contrast helps distinguish data points for low-vision users, and a proper tab order allows keyboard-only navigation to follow a logical flow. On the Microsoft Power BI Data Analyst PL-300 exam, this topic tests your understanding of inclusive design under the “Optimize a model for performance” domain, often appearing as a select-all-that-apply question. A common trap is choosing “use many colors” or “add 3D effects,” which actually reduce clarity and create visual clutter. Remember the mnemonic CAT: Contrast, Alt text, Tab order—these three keep your reports accessible and your exam score high.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
